1 Corinthians 11:5-6
11:5 But any woman who prays or prophesies with her head uncovered disgraces her head, for it is one and the same thing as having a shaved head.
11:6 For if a woman will not cover her head, she should cut off her hair. But if it is disgraceful for a woman to have her hair cut off or her head shaved, she should cover her head.
1 Corinthians 11:15
11:15 but if a woman has long hair, it is her glory? For her hair is given to her for a covering.
